Features for YIY Lithium battery 

*    Due to the demand for energy saving strategies, YIY delivers a full range of battery power systems with multiple nominal voltages (12V/24V/48V etc.). It is smaller in size and lighter in weight, but it has longer cycle life, temperature durability is stronger, and energy storage is more efficient. With the accurate and reliable battery management system (BMS), our lithium battery power system is a better solution for achieving highest efficiency and reliability. After years of practice, we have the most extensive experience in backup power supply in the industry, and we will continue to provide the best battery products.

*    YIY high-quality cell brings higher conversion efficiency of the energy, the common performance of the B Level batteries which are most common in the market will only have 75% percentage capacity left, however, we will remain 99%.

Advantages for YIY LiFePO4 Battery

*   Energy density is high. The volume and weight of lithium battery is 1/3 to 1/4 of the traditional lead acid battery with the same capacity. Energy conversion rate is 15% higher than that of a traditional lead acid battery, the advantage of energy saving is obvious. Self-discharge rate < 2% per month.

*   Broad temperature adaptability. Products perform well at a temperature of -20°C to 60°C, without air conditioning system.

*   Cycle durability for a single cell is 3500 cycles, which is 3 to 4 times more than the cycle durability of a traditional lead acid battery.

*   Higher discharge rate, faster charging and dischargingWhen there is a need for backup power supply for a period of 10 hours or less, we could reduce up to 50% of the capacity configuration, comparing to lead acid battery.

*   High security. Our lithium battery is safe, electrochemical materials are stable, no fire or explosion under extreme conditions such as high temperature, short circuit, drop impact, piercing, etc

*   Optional LCD digital display. The optional LCD digital display can be installed at any location and displays battery voltage, capacity, current information, etc.
